    New BIO typeclass checklist:

    [ ] - add syntax to `Syntax2` with the same name as the type
[ ] - add syntax for new root's `InnerF` with the same name as `InnerF` in `Syntax2`
[ ] - add new attachments in `RootInstanceLowPriority*`
[ ] - add conversion from itself to its `InnerF` to `RootInstanceLowPriority*`
      (conversions implicit priority: from most specific `InnerF` to least specific)
[ ] - add conversion to equivalent cats typeclass if applicable in `CatsConversions`
[ ] - update hierarchy graph above, re-render SVG
[ ] - add syntax tests in `SyntaxTest`, runtime tests if applicable
    ,

    Real and raw (direct inheritance) hierarchies differ because of implicit ambiguities caused by inheritance: https://typelevel.org/blog/2016/09/30/subtype-typeclasses.html However, since Scala 3.7, the ambiguity problem has been resolved on Scala 3 using inverted given prioritization: https://contributors.scala-lang.org/t/joining-the-dots-on-recent-implicit-prioritization-changes-and-some-scala-history/6814/3 So, when or if we drop support for Scala 2, we can revisit the design, remove InnerF pattern and make real and raw hierarchy match.
